Question

Samantha was training to play basketball. She threw the ball 19 times. Gabrielle wrote down all Samantha's throws and for all the ones who got in the basket she added 5 points. For all the throws that weren't successful, she got rid of 3 points. At the end Samantha got 55 points. How many times did Samantha throw the ball in the basket successfully?

Answer 1

15 times.

Explanation:

5 x 14 = 70 points

3 x (19-14) = 3 x 5 = 15 points

70 points - 15 points = 55 points.
